The name may say Black Feather, but the Japanese spelling is different from the Black Feather archetype. The Japanese name of Black Feather Dragon does not include " B F ", so it is not a part of the archetype. This was first pointed out by Deltaneos on the Yu-Gi-Oh! Wiki: " just pointing out "Black Feather Dragon" is not a "Blackwing" (ＢＦ(ブラックフェザー), ''Black Feather'') monster. Its Japanese name is spelled "マシンナーズ・フォートレス", which doesn't contain "ＢＦ(ブラックフェザー)"."
